To a whom it may concern.-

Be it known that. we, FRANK H. BROWN and JOHN E. HANRAHAN, of the cityof Baltimore and State of Maryland, and GEORGE A. BOYDEN, of MountWashington, in the county of Baltimore, State of Maryland, citizens ofthe United States, have invented certain new and useful Improvements inMatrices for Casting Spaces and Quads, of which the following is aspecification.

This invention relates to a matrix from which type spaces and quads areto be cast; and the object of the invention is to provide a matrix forthis purpose which may be used in the same mold in which the type withchar acters are cast.

It is to be understood that spaces and quads should be shorter in lengththan types having projecting characters, and in order to cast suchshorter spaces and quads in the same mold-cavity that is employed tocast the types with the characters the length dimension of the cavitymust be shortened. By this invention, therefore, we provide a space andquad matrix plate having on its casting side a boss which when broughtinto the position to close the end of the mold-cavity will project ortake into said cavity and shorten the latter to the extent to which ithas entered said cavity. Thus the length of the mold-cavity having beenshortened tlxe type-bcdy cast therein will be correspondingly shortened,and these type-bodies con stitute the spaces and quads.

The construction or operation of the mold parts is immaterial, it beingunderstood that when they are in the casting position the improvedmatrix Will have position at one end of the moldcavity, and the boss orprojection on the matrix will enter said cavity.

The invention is illustrated in the accompanying drawings, in which-Figure 1 illustrates a face view or front elevation of a space or quadmatrix, and Fig. 2 illustrates a side or edge view of the same.

The improved matrix consists-of a plate 1 of such dimensions as toreadily coact with the mold mechanism. The bro ad flat side of thismatrix-plate, which is to seat against the 50 end of the mold-cavity, isprovided withaproor boss 2, which is to enter the moldcavity, therebyshorten its length dimension. The flat outermost face of this projectionor boss forms the top or end of the quad or space that is cast in saidcavity. The vertical dimension between 3 and 4 represents the bodywisesize of the space or quad, and all sides of said boss are spaced fromthe edges of the plate.

It will be understood that any size projection or boss may be on thematrix-plate.

By this invention changes can be rapidly made to cast spaces and quadsfrom the same mold mechanism that produces type characters.

This invention enables spaces or quads to be produced from the same moldmechanism that casts the type of the same bodywise size and withoutrequiring skilled adjustment of the parts, it only being necessary toremove the matrix which has the type character and substitute theimproved space or quad matrix.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. A matrix for individual-typecasting machines, comprising a platehaving at its broadest fiat side a projection or boss of smallerdimensions than the said flat side of the plate and all sides of saidboss being spaced from the edges of the plate, whereby a space or quadof a size equal to the outermost face of the said boss may be cast in anordinary type-mold cavity.

2. A matrix for converting an ordinary type-mold cavity into a cavityfor casting spaces or quads, comprising a fiat plate having at itsbroadest side a rectangular boss adapted to shorten the length dimensionof said mold-cavity.

In testimony whereof we affix our signatures in presence of twowitnesses.
